don't know if this will help or not, but my breeder said that if Badger gets Diarrhea (sorry can't spell), then feed him a chicken and rice diet (cook the chicken, boil the rice put the chicken with the rice and give some to him including the rice water as this has benefits.), haven't had to try this yet (only had badger 3 days), but maybe worth a try, see what others on here think. another thing just make sure he is drinking water, as I've heard puppies can get dehydrated quickly.
